Wrinkle patterns in active viscoelastic thin sheets

Abstract
A viscoelastic thin sheet driven out of equilibrium by active structural remodeling develops a rich variety of shapes as a result of a competition between viscous relaxation and activity. If active processes are faster than viscoelastic relaxation, wrinkles cannot elastically relax and the sheet is inherently out of equilibrium. This non-equilibrium regime is of particular interest in biology as it allows the system to access morphologies that would be inaccessible if restricted to the adiabatic evolution between configurations that minimize the elastic energy alone.
